Geopolitical design thinking: this week Paul and Rich talk to Jeremy Pam, an international relations expert whose career has taken him from Wall Street to Iraq and Afghanistan to MIT to his current position at Columbia University’s Saltzman Institute of War and Peace Studies. The conversation ranges from sovereign debt relief to New York subcultures to working in a warzone to the Homebrew Computer Club, and they draw parallels between the tech world and geopolitics—and how to reconcile with outcomes your data models never predicted.
